Be it known that I, HENRY AUoHU, a cit-ii zen of the UnitedStates,residingfat Empoli# rium, county of Cameron, and State of Pennf2Sylvania, vhave inventedl certain 'new'v and l 'il it,. under pressure,through anozzle ,from which the gelatin emerges as a continuous I'nozzle, to vthereby forni the cartridges WhichyMachines` of thecharactersetjforth rope, the diameter of'which may be "from less than an inchtojupwards of jtWo inches, this, ropebeingcut. into suitable lengths,usually about eight-inches, after emergence from the are thensuitablyWrapped 4so as to be ready for.,commercialuse.,A

'have usually employed a horizontal screw, termed by skilled Workers in.explosives afpacking' screW,.y for forcing the explosive gelatin throughthe nozzle, and associ-atedwith this packing screvvf means have beenemployed t o,feed the plastic gelatin to the screw. It

has heretofore heen proposed to ein loy a feeder for causing :thegelatin to be'fed to the packing screw, which Will more or less auto--rnfatically yield if the pressure of the feeder v .ecn-the gelatinbecomes so great that further augmentation would render continuedoperation of the4 machine dangerous on account o'f the subjection of thegelatin to toogreat pressure With Aincident heightening of the.`"temperature of the mass-and frictional action s Iny of thepacking-screw land nozzle thereon. lmachines of'A this character, itisfdeslrable to be able toquicklyregulate the action'of-the feedingmechanism so that as'ba.tches of .the

explosive gelatin arev introduced; to -thefefedingmech anism, theconditions of fee'dmay be vof'"t-liis character havenotheretofo'redoeeny ,l and lhave for one4 object vof my-m- .changesorrvariations in' the feedin machines 'fthe provision of a machineforforrncartridge rope-from explosive gelatin 4permit cleaning l o,patentes ifrafeh 1o, isos.

The mechanism which I provide v.for con e trolling orregulating thefeeding of the'gelav tinis 'capable of bothl automatic -andh'andregulation, in both'aspects of which it is, so

far as I am aware, entirely novel over any A thingheretofore employed.This nieehan ism is so constructed and arranged thatthe feeder. itselfwill automatically stop Whenever the pressure upon the gelatinbecomestoo great, rather than mere-lyv ease 'up o'r lessenv the feeding action,has heretofore been proposed' to beI accomplished, and this 'function isobtainedby the use of afnovel. .fonm of friction' gearing, the' gears ofwhich ybecome instantlydisengaged on the slightest endwise movement ofthe feeder shaft, such erldwise movement being very Ismall in magfnitudeandis permitted by having the feeder l'shaft adapted for only suchendWise move?v ment' as is' ,usual in sliafting to preventv any bindingaction at thesha'ft bearings.

The action of the feeder ofthe present inf vention is also easily andrapidly regulated by.; the e'mplo` nient of novel vmeans ,for changingthe re ative positions ofthe friction gears so that the feeder maybedriven faster or Y slower to' increase or diminish the feed'. of xthegelatinfby hand coi'itrol, thefoerator being enabled to instantly changete feed as lievvatches it so thats'uccessivebatches of the explosivegelatin ymaybefed v faster or sloweraccording toftheir consistencyandthe requirements-of ope`ra tion. A l

Another object ofiny inventionis th'epr`4 vision of a novel form offeedhoppe'rhaying' a removable. upper part permitting ra idr andeasyremoval of the feeder Withinthe ,iop'gper when it is desired o1crleazn said "ftrts and also provide-an im roved 'construction perlmitting removal o the feeder. shaft When-y still further Obj ect f of.

gig. 12 is adetail section online 12-12 of The metal base 1 ofthemachine is rovided with bearings or boxes. 2 in whic is journaledA thepacking screw shaft 3, which is of steel, ln e the packing screw itself4 has a short shaft-section 5, the shafts 5 and 3 being connected by ascrew coupling 6, the

' threads of which are so arran ed that rotation of the packing screwand t e shaft tends `to tighten the joint 6, In machines for packingexplosive gelatin, it `has been usual to form the packing screw and itscomplete shaft from `a single piece of bronze, as 'this material, whenin contact with the gelatin, is not adapted to cause pensive alloysincrease the cost of the machine andso to cheapen suchcost, as well asto permit' ready detachment ofthe packing screw and its short shaft, Ihave provided the union or coupling 6. It is desirable to employ arubberor pa erwasher 6' between 'the parts of the coup ing to insure a tightjoin - To prevent too far entry of the p'ackin screw 1n its leadorBabbitt metal case 7 an nozzle 8, the collar 9 being also employed, aft3, but in order'to adjust the packing screw 4 ineniploying a movablecarriage havingl bear-- invention are recited inthe appended claims.

6 is a etail view looking toward the left of hopper..

to the inside of the nozzle without touching 'the latter, I provide anadjusting screw 11 threaded through an extension or lug 12 on base 1 andbearing against the rear end of shaft 3. When working on small sizedcartridges, it is advisable to have the. packing screw. penetrate asclose to the inside of the nozzle as ossiblewithout touching it, as thegelatin w' l then be forced through the nozzle with woul otherwisearise, be relieved.

The nozzle 8 and collar 9 are bolted to gether and the collar 9 is alsodetachably connected to. packing screw case 7, permitting separation ofthese parts for purposes of cleaning. f'

Secured by splining, or otherwise, to shaft 3 are belt-pulleys 13 and14, the latter being connected by belt 15 to a clutch-pulley 16 on aline Vor counter-shaft 17, a ha'nd lever 18 being provided for throwingthe clutchpulley 16 into and out of o erative engage- 'm'ent with shaft17, where y the machine maybe started or stopped.

Risin from base 1 and suitably bolted thereto '1s a yoke-upright 19 towhich is bolted a horizontal frame-piece 21. This construction affords arigid bracing for the yokeupright 19 and also a support for certalnparts described presently. Bolted to the top of the packing screw case 7is a conical hopper 22 whose upper part 23 is in the form eaterfacility,.and the pressure which\ of a cylindrical ring which isdetachably connected to the lower part thereof by lthe iianges'and bolts24, permitting'removal of the upper part for purposes of cleaning. The

ring 23 is cut out at one side Vto facilitate introduction of thegelatin into the hopper.

. Detachable shaft-boxes or bearings 25 and -26 are provided oncrossepiece 19L and apex of yoke-upright 19, the said boxes being ver'-tically alined in the vertical vaxis of the The lnumeral 27 designates4the lfeede;` shaft, which is journaled in the boxes or lars 28 and 29above and below the bearing 25, the collar 2 8 suspending or sustainingthe feeder shaft and the feeder, and the collar -29 holding the feeder'`shaft against vertical movement except such slight or minimum ioo 1robearings 25 and 26, said shaft carrying olendwise play of said shaft asis usual in any shafting to prevent binding where collars are employed.These' collars are held to the shaft by suitable set screws and turnwith said shaft.

The feeder is made of bronze and com- I iblel similar to the coupling 6andhaving the rub- 130 senses to work nearer to or far-ther from thehopper' walls, according to the Wish of the operator, this beingaccomplished by shifting the collars 28 and 2Qv andre-clamping theminthe desired position.

Rigidly secured to shaft 27 by the' key. 33 isby preference perfectlyflat.

Mounted upon and connected to the framepiece 21 are bearing stand ards"35 which have 2 0 horizontally 'and vertically adjustable bear ings 36,made so by' the four screws 36a, 'mounted'in which is a horizontal shaft37. Splined upon the proj ectingend of shaft 37 by a feather 40 carriedby the shaft, is a friction a fri ction-wheel 34, the lower face ofwhich is 25 wheell 39 which may, owing to said splined connection 40,be. slid lengthwise ofthe shaft by aracked shifter 41,a havinga yoke 41bengaging a groove 41@ in the hub of wheel A hand wheel 41X, on -thc sameshaft with a pinion 43, engaged with the rack, affords means forshifting the wheel 39 on shaft 37. The friction-wheel 39 be'ars againstthe flat under face of the friction-wheell 84 and, as

the shaft 37 is in' the saine planeasshaft 27,

. the frictionwvlieel 34 will be driven faster or sl ower a'ccording asthe friction-wheell 39 is moved toward or away freni shaft 27. 'Theshifting ofifriction-wheel 39 may be instantly accomplished -bythe'opera'ton-who thus has 4o the rate of rotation of the feeder underabsolute control so thatif the operator finds that the feeder iscrowding the packing'screw by feeding too much gelatin to it, or if theconsistency of the' gelatin demands a different v rate of feed, theoperator can'at once change .the feedas 'his experience may dictate isad vi-sable. f Abell;A 42 connects pulley 13 with a pulley V44 on shaft37.

5 0" ln the operation of the machine the feeder within the hopper22-;23, forces the gelatin to the packing screw 4, which in turnpresses.

the gelatin outythrough the nozzle 8 in the 'form of a'continuouscartridge rope, which is severed intoI marketable lengths of. abouteight inches and afterward wrapped. As previously explained, thev shaft.'27 is c apable o'fa very slightA endwise movement' which is nogreaterin magnitude than is common in any shaft having collars to limit itsendwise or lengthwise thrust as some play is necessary in .shafts thusheld, in order to preventbinding of the collars on the bearing;

This 'slight play, which is only a "very small .fraction of' an inch, issufficient,' however. to

cause the face offricztionwheel 34 to .lift clear 'of'engageinent withfrictiorwvheel 39, when the pressure ofthel feeder upon thegelatinin thehopperheconies so greatth'atthe reac-4 tionary effect overcomes thecombined Weight A'70 ofthe feeder, feeder shaft,v friction-wheel,

etc., and hence the feeder will automatically stop rotatingby reasonofthe disei'igagenient of the friction-wheels34 and 39 When'th'e feedbecomes too great-1'.' Immediately the 75 pressureon'the gelatin isrelieved 'some vi/laat@L the friction-wheel 34 drops slightly and againbears on friction-.wheel 39- and the feeder' then resumes its rotationThis action is en# tirely automatic and is radically distinct 80 fromany feeding mechanism which merely slows down as has been thecaseheretofore.-

Referring now -to Figs. 8, 9, and '10, the machine therein shown is inall respeets`simi. lar to the machine heretofore described -asg5 regardsthe feeding mechanism' and allied devices, but the louer part of themachinel embodies certain different constructionspermitting relativeshifting-of the packing screwa-nd its case to facilitate cleaning.v Thebase of the. machine' consists of'a bese" part 70,

\vhic.h.sup}' orts the packing screw case 7 and is bolted jthercto, andateil bese-piece 71, the part-s 70 and 71 being rigidly connected byparallel guide-rods 72b The sub- 95. base 73 has sleeves 74, which'-slide on the guide-rods 72. this sub-base carrying bear'- ings 2 in-which the packing screw shaft 3 Y is journaled and coupled at 6,heretofore set forth. A screw 11a 'serves -the purpose of side of thelug 12 instead of Abeing on opposite sides thereof. To shift thesub-basc,'

which may be termed carriage 7 3 back and 105 forth on the rods orguides 72, a screw 7'5 is' employed, the same being threaded throughthe. tail-'piece 71 and having a head 'i6 s'wiveled in lug 12'bydetachable plates 76 so that the carriage or sub-base may be :ref:treated lwell as `advanced. il suitable hand-wheel 77, carried bythescrew, is used for advancing or retreating'the carriage.

To. prevent too vfar insertion ofscren"` 4 in case 7, lanadjustablescrew 7S is employed -115 i constituting an adjust-able abutment againstwhich the sub-base or ca'rriage'73 will strike when' the packing screwis sufliciently'far advanced in its case. A removable pan 79 -ni'ay beset underneath the place where the 120' packing screw will be positionedWhcnreltree tedfronr its .case lsothat any loose pieces of gelatin vwillbe caught and-not allowed to drop'around and gcton the parts. As will beseen from Fig-` 9, when the packing sere-'w is retreated from its case,it is cxf posed nnd`both it and the interior of the pecking screw maybc' rer-(lily cleaned. In shifting thc-sub-misc 7:5, the belts 15 and 42are unshipped from thc'pulleys 1 4 and 13. 130' 100 the screw'11, but isa little differently ar- 'ranged as the head and the tip are on thesameThe-engagement of `the wheels gli and 39`i' device and friction Wheelbeing adapted for kvpreventmthe paddles of the feeder` from everdropping and touching the inner sides of the `hopper or thepacking-,screw and supplements the suspending functions of the collar28.
